IMPRVEMENT IN WATERBWHEELS.

Specification forming part of Letters Pat-ent No. 147,357, dated February 10, 1874; application filed December 2U, 1873.

To all whom it may concern:

Be it knomi that I, JOHN L. Bann-s, of Cocolamus, in the county of Juniata and in the State of Pennsylvania, have invented certain new and useful Improvements in Tater- Vheels; and do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings and to the letters of reference marked thereon, making a pa-rt of this specification.

The nature of my invention consists in the construction and arrangement of a water-wheel and scroll, as will be hereinafter more fully set forth.

In order to enable others skilled in the art to which my invention appertains to make and use the same, I ill now proceed te describe its construction and operation, referring to the annexed dranngs, in which- Figurc l is a vertical section of the scroll, with a side view of the wheel. Fig. 2 is a horizontal section of the scroll. Fig. 3 is a plan view, and Fig. 4 a bottom view, of the wheel. Fig. 5 is a plan view of the scroll. Fig. 6 is a longitudinal section of the wheel.

A represents the body of the scroll, which may be made of wood or metal, as desired; but I prefer to use wood, and in that case the upper surface is covered by a metal plate, B. At the rear of the scroll A is a frame, C, within which is a vertically-sliding gate, l), for closing the entrance to the scroll. This gate bears at one end against the body of the scroll, and at the other end against a iiange, a, projecting from a slide, E. The slide E is moved ,out and in, as will be hereinafter described,

and its flange a, at allptimes, forms a bearing for the gate D, so that the pressure of the water will keep the gate tight. The waterpassage G in the scroll gradually diminishes inwidth from the entrance to its extreme end, and is gradually ascending to' said end b, the

`water acting upon all the buckets of the wheel,

but one, at all times. This water-passage is partially covered by the plate B, in which is a curved opening, d, allowing the water to pass from the scroll to the wheel. This opening d is constructed as shown in Fig. 5, to increase in width in the same direction as the water passage diminishes, so that at or about the point :c the two become equal. By this con struction of the water-passage and opening through which the water enters the wheel, the force of the water is perfectly equalized from one end of the scrolhpassage G to the other. H represents a gate within the water-passage Gr, hinged at y, and its other end inserted in a forked arm, I, attached to the inner side of thc slide E at or near its inner end. The gate H moves under t-he plate B at all times, and is operated by the slide E, to contract or enlarge the entrance to and a part of the waterpassage Gr, thereby regulating the amount of water passing in according to the speed desired, or the amount of machinery to be driven. The slide E is, on its outer side, provided with a rack-bar, c, into which gears a pinion, j', on a vertical shaft, h, and this shaft is to be con nected with an ordinary governor, so as to regulate the slide E and gate H automatically. By means ot' the arm I, which forms the connection between the slide E and the gate H, the end of the gate II can be moved to a certain. point without moving the slide any greater distance, and hence the entrance to the scrollpassage G can Vbe made considerably less in width than if the gate was attached directly to the slide. The center part A of the scroll is not made on a true circle, but has a swell or eccentric from z to z, as shown in Fig. 2. The wheel is composed of a hub, J, a series of buckets, K K, and a rim, L. The hub J is in tlie form of an inverted cone, to the sides of which the buckets are attached. curved, as shown, at the top and outside, the smaller lower end of each bucket passing into the larger front or upper end of the next bucket, and the outer curved sides of the buckets resting upon the rim L. The hub J and rim L are of such relative sizeI that the upper edge ofthe hub will be perpendieularly above and on a line with the inner ed ge of the rim, whereby a proper curvature ot the bucket is obtained, so that the water will form a perfect percussion, and act both against the top and side of the bucket, its entire force being spent and exerted on the bucket before it is dis charged from the same.

Having thus `fully described my invention,

The buckets are what I elaiin as new, and desire to secure by in combination with the gate D, as and for the Letters Patent, ispurposes described.
